To all whom it may oonccm-.'

lie it known that 1, WILLIAM E. HALE, a citizen of the United States,residing at Fort Washington, in the county of Montgomery and State oi"Pennsylvania, have iii-- vented a new and useful Improvement inSkip-Hoist Equipment, of which the following is a specification.

Objects of the present ihvention are to insure proper clearance betweenthe descending skip bucket and the more especially in cases where thelatter may shift or be shifted a little after having been put in closedposition by the ascending bucket, to avoid any bumping action be tweenthe bucket and gate and to provide for smooth sliding contact betweenthem, and other objects of the invention will ap pear from the followingdescription.

The invention maybe said'to comprise a cam shoe devife'e carried by oneface of the bucket and projecting beyond the lower edge and toward thecenter line of the bucket to insure proper positioning of the ate toafford celarance for the passage of the descending bucket, with orwithout an outwardly sloping upper portion for shockless contact withthe gate.

The invention further comprises the improvements to be presentlydescribed and finally claimed.

In the following description reference will be made to the accompanyingdraw.- ings forming part thereof and in which Figure l is an elevationalviewof a skip bucket showing the cam shoe device applied to one facethereof.

Fig. 2 is an elevational View illustrating the gate in closed position.

Fig. 3 is a similar view showing, the gate in open or loading position,and

Fig. l is a view similar to Figure. .l showing a portion of the gate andits hook or, in other words, it is a face view looking to ward the leftin Fig.3.

pivotal loader gate,

portion 4 of the cam shoe The cam shoe 1 is shown as provided with 00 anoutwardly sloping upper portion 4. As shown the cam shoe device isduplicated and the 1parts are so spaced as to clear the hook 5 o thegate 6, F g. 4. The ho0k'5 as shown includes two ion and permits thehook to elongate. and contract. The gate 6 is pivoted to the chute 7 asat 8, and as usual is orlinay be counter wei hted as at 13. The skipbucket 2 is '00 me e to ascend and descend on the skiphoist structure 9for which purpose wheels 10 and a hoisting bale 11 are shown. There isnothing particularly new in the gateand skip bucket in themselves andthey are sub- 06 ject to wide difierences in form of embodiment.

The mode of as follows:

In ascending the outwardly sloping upper I0 device turns the gate upwardin closed position, as shown in Fig. 2, in which positionit is supposedto reman until the descending skip bucket 2, acting on the hook 5, turnsit downward so 7| that-itcomes intoloading position as shown in Fig. 3.However, the gate does not al- Ways remain in turned 11 closed positionbut moves or is moved slightly dowIiwa-rd out of that position and whenthat happens so the inwardly projecting part 3 of the de-.. scending camshoe device turns the gate upward into its proper position so thatclear-- ance is provided between it and the bucket, and the outwardlysloping upper portion 4 operation may be described of the cam shoedevice provides a means for smoothly diverting the gate from the bucketif the gate should tend to contact with the bucket after the part Shesturned the gate upward and cleared it. The invention is not limited tomatters of inereform or otherwise than the prior art and the appendedclaims may require. I claim: 1. Skip hoist equipment having in com- 95."bination a pivotal loader gate, an ascending and descending skip, bucketadapted to close and open the gate, and a cam shoe device parts orsections con- 55 i) nected by a spring 12 which acts as a'cu'slb Qcarried by one face of the bucket and projecting beyond the lower edgeand toward the center line of the bucket to insure positioning of-thegate to afford clearance for B the passage of the descending bucket.

2. Skiphoist equipment having in combinationa pivotal loaderugate, anascending and descending skip bucket ada; ted to close and open thegate, and a cam shoe device carried by one face of the bucket and projectingbeyond the lower edge and toward the center line of the bucketand provided with-an outwardly sloping upper portion.

WILLIAM -E. HALE.
